Building 7 of the world trade center was not hit by a plane and collapsed at free fall speed with no resistance around 5:30 pm that day. The owner of the building in a later interview said he "pulled" the building. here is a 20 sec video of silverstein http://youtube.com/watch?v=7WYdAJQV100 There is so much evidence it will make your head spin. BBC reports building 7 falling 20 minutes before it happened with a live report, and when they realized the building was in the background cut away from the screen. Here is a link to the scientific evidence for 9-11 being an inside job. http://stj911.org/
